IMPROVED DERRICK.

To all whom it may concern.-

Be it known that l, SETH TURNER, of Onarga, in the county of Iroquois and State of Illinois, have invented a new and improved derrick for elevating hay, grain, &c., for loading, stacking, or mowing the same; and l do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accoml'ianying drawing, forming part of this specification.

The drawing represents a perspective view of my inveution.

This invention relates to a new and improved derrick, arranged in such a manner that. it may revolve,and provided with a fork, tackle, spring, and guide, as hereinafter fully set forth, whereby the hay or grain maybe elevated to anydesired height and then swung around over the stack, rick, cart, or mow, and discharged, and the empty fork then lowered, to be again loaded, elevated, and discharged.

A represents a framing, constructed in any proper manner to insure strength with lightness, and B is a shaft, which is placed vertically in the framiug A, its lower end being stepped in a cross-piece, a, at the bottom of the t'ramin g, the shaft being allowed to rotate freel y in the latter.

At the lower end of the shaft B there is a metal ferrule, C, which is notched at suitable and equal distances apart, as shown at ax, and D is a rod, which is fitted in guides b, on the cross-piece a, and has a spiral spring, E, upon it, said spring having a tendency to keep the rod D pressed toward the ferrule (J. The rod D has a cord, F, attached to it.

To the upper end of the shaft B there is attached an oblique or inelin'ed rod, G, which is braced by a bar, H, and I is a rope, which runs through a sheave or pulley at the Outer end of G, said rope passing through the outerend of an adjustablc arm, J, on the top of the framin g A, and through a guide, e, on the cross-piece a, near the lower end of shaft B.

The arm J is slotted longitlulinally, as

l sh own at f, and abolt, g, passes through the slot (finto the framing. This mode of attachment ,i admits of the arm J being turned or adjnsted either to the right or left, and also of being virtually lengthened or shortened, as may be l required.

1 approved horse hay-forks may be einployed. This fork, after being loaded, is elevated bya i horse attached to the opposite end of the rope 3 I, and when the fork is elevated to the desired height the operator pulls the cord F, which causes the rod D to be (lrawn out from one I of the notches a* in the ferrule G, and the loaded fork is swnn g around over the stack, rick, cart, or mow,and, the horse being stopped, I the operator pulls the trip-cord of the fork, and the hay or grain is discharged. The horse l is then backed, the shaft turned back to its I original position by pulling on the trip-cord, f the rod d being forced by the spring E into a i notch ax of G, to prevent shaft B from turning. The fork is then lowered, and the operation repeated.

The arm J is adjusted relatively with the shaft B and the place where the hay or grain is to be discharged, so as to prevent the shaft being turned more than the required distance each time the fork is swung around over the place where the load is to be discharged, and

,l by lengtheni n g land shortening the arm J the speed of the turning of shaffi B for that ,i purpose may be varied as desired.

l' I claim as new and desire to secure by Letters Patent The rotating shaft B, provided with the oblique arm G and titted in the framing A, as

1 shown, in combination with the adjustable l arm J and the rod or catch D and the notched ferrule C, or their equivalents, for securing' I the shaft B, all arranged and used in connection with a horse hay-fork andtackle, substantially as and for the purpose set forth.
